2015 Priorities
Triennial Review Update
• Adoption of dissolved metals criterion
– Represents more toxic fraction
– Less conservative than current use of total metals
• Hardness-dependent metals equation
– Allow use of median hardness to calculate permit limits
– Provides greater flexibility
– Permittees benefit from localized, site-specific adjustments
• Addition of acute standards
– Clarity in our assessments of impaired waters
Triennial Review Update
• Addition of streamlined site-specific criteria
– Use of Water Effects Ratio
• Retain action level for copper, silver, and zinc
• Eliminate manganese standard from WS-I – WS-V Rules
• Retain existing chlorophyll a standard
Triennial Review Schedule

November 2014 – Hearing Officer’s Report to EMC
Late 2014 – Early 2015 – Rules Review Commission
2015 – State Adoption
Package to EPA for Approval
Nutrient Criteria Development Plan
• NC & EPA reached “mutual agreement” on exisiting
nutrient plan in June 2014
o Plan includes milestones through 2025
• Does not commit NC to developing one standard for all of
NC for nitrogen and phosphorous
o Allows NC to develop standards regionally
• Standards developed through
o Stakeholder process
o Advice from a Science Advisory Council (SAC)
o Advice from a Criteria Implementation Committee (CIC)
Nutrient Criteria Development Plan
• Process begins on 3 representative waterbody types
o High Rock Lake (Lakes & Reservoirs)
o Central portion of the Cape Fear (Rivers & Streams)
o Albemarle Sound (Estuaries & Sounds)
• Waters with existing nutrient strategies will not be
revisited under this plan
EPA’s Proposed Electronic Reporting Rule
Published July 30, 2013
• Requires entities to submit reports electronically
• EPA anticipates issuing the final rule in early 2015
• Two-Phase Implementation Plan: electronically report
o DMR data 1-year after rule’s effective date
o Other required reports 2-years after rule’s effective date
• Entities report to DWR if >90% participation is achieved
• DWR’s eDMR Participation Rate:
o 1st QTR 2014 = 0.7%
o 2nd QTR 2014 = 7.6%
o 3rd QTR 2014 = 9.3%

Shortages are based on the projected demands and new alternatives as supplied in the
local water supply plans. DWR staff for this analysis has not made a determination if the
projections are reasonable or the likelihood that an alternative is practical.

Is NC Prepared for the Next Drought?
• NC Drought Management Advisory Council
o Improve coordination, provide accurate and
consistent information, based on technical data to
address varying conditions in designated areas
• Water Use During Drought Rules
o Minimize harmful impacts of drought by establishing
min. standards and practices for water use
• Water Shortage Response Planning
o Establishes authority for declaration of a water
shortage, defines different stages and outlines
appropriate responses for each stage
o DWR approved 550 of 561 WSRPs

Integrated Water Quality & Quantity Planning
• Knowing the location and quantity of North Carolina’s surface and groundwater
resources, as contrasted with surface and groundwater quality, will aid the state
in applying best conservation management practices at a local, regional and
state level.
• The integrated approach helps logically bridge the work of other DWR Sections
with each other so that water resources evaluation and assessment within
North Carolina is much, much more seamless, and water resource operations
more efficient.
• The new relationship between water quality and NPDES facilities and water
quantity and NPDES facilities, will expedite consideration of water reuse
applications as part of a comprehensive water resources conservation package.
• This integration provides DWR end users with “better, faster, cheaper” data and
answers to water resources questions, and will help to establish North
Carolina’s water security which will only help the state’s economy grow.
